RAYMOND C. DUDLEY, OF CHICAGO, ILLINOIS.

CAR-ROOF.

Specification of Letters Patent.

Patented Sept. 1, 191 4;.

Application filed January 11, 1913. Serial No. 741,382.

To all whom it may concern Be it known that I, RAYMOND C. Donnie a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Roofs, of which the following is a specification.

The invention relates to outside metal car roofs for freight cars, and has .for its principal objects to simplify the construction of such roofs, with economy in manufacture, and at the same time to increase the strength, efficiency and durability of the same. And with such objects in view the invention consists in the parts and combinations thereof hereinafter set forth and claimed.

In order to make the invention more clearly understood there are, shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of example have been delineated.

In said drawings :-Figure 1 is a plan .view, partly bro-ken away, of a portion of a .car roof embodying the invention. Fig. 2 is an'en'd View of the same. :Fig. 3 is a cross sectional View of the same on line III-III of Fig.1, on'a larger scale, and partly broken away. Fig. 4 is a similar view of the central part of the roof, on line IV, IV of Fig. 1. Fig. 5 is a perspective view of the outer end of the seam cap. Fig. 6 is a horizontal section on line VI-VI of Fig. 7. Fig. 7 is a side view of a portion of the car, the running board and its saddle being shown in section. Fig. 8 is a longitudinal. vertical, sectional view of a portion of the car near its end and on line VIII-VIII, of Fig. 2, the running board and saddle being shown in section. Fig. 9

is a vertical transverse section on line IX- IX of Fig. 10. Fig. 10 is a side elevatioii of a portion of the car, showing additional securing devices for the eaves ends' of the roof sheets and seam caps. Fig. 11 is a perspective view of one of the roof sheets. Fig. 12 is a sectional view showing'a modified construction of sheet flange and seam cap, combined with the sub-carline.

Referring to the"drawing's :-1 is the ridge pole of the freight car roof, connected with the side plates 2 by carlines 3. The carlines are or may be of metal of L-shape the inner corners thej sh (Fig. 1) in cross section extending across the car from one side late to the-other, to which they are-secured through flanges 5 formed on the ends of the carlines. The carlines pass beneathv the ridge pole, to which they are secured by vertical bolts 6. The top sheathing of the roof is shown at 7 consisting of matched boards running transversely or longitudinally, the latter hein the arrangement shown, the sheathing 7 be rafters or an' usual or suita le means. The side sheat ing. is 'shownat 8, its upper part bein attached to the sid eypla teis 21nd overlaid %y the fascia 9. "Connected by bolts 4 passing ing s'u ported the side plates are the end plates 10 fcar'rys top sin-face of the roof sheathing 7 The.

outer edge of the roof. sheet 15 is formed with a bent down flange 16 having end poitions 17 which extend longitudinallyofthe car beyond the main flat body of the sheet. The side edges are each formed with an upwardly extending L-flange consisting of an upwardly extending part 18 and an outwardly extending part 19. The inner edge of the sheet is formed with a U-flange consisting of an upwardly extending part 20 and a downwardly extendin part 21; At

. 65 s p p ly notched and portiorrs- 22 of the flanges are bent around to form water tight corners. The roof'sheets 15 are laid side by side along the car on both sidesiof'the ridge, each sheet extending from the ridge to' the caves of the roof. The U-flanges' 20, 21 of the contiguous sheets are interlocked with each other at the ridge (Fig. and the flanges 16 lie on.

ening the roof .eter. The side flanges 18, 19 cf the plates are supported by and embrace supercarlines 25 which rest on the roof sheathing 7 between the vertical flanges 18 of contiguous sheets and extend from ridge t caves of the roof. At the ridge the supercarl nes of the two sides of thereof are mortised together (Fig. 4) and pivotallytheld in'positio'h by the said bolts 6, which pass ye tically through holes in themortised ends. The supercarlihes are "otherwise horizontally free relative to the roof andmay oscillate therepn as maybe by the distortions of the roof in' service. The contiguous flanges 18, 19 of each pair of roof sheets are overlaid in a,

.yvatertight manner embraced and united by seam caps 26 (Figs. 5 and 8). Each seam the supercarlines with its sheet flanges 18, 19. At its inner. end the side flanges 27 are removed from the seam cap (Fig. 5) leaving its top portion extending in the form of a tongue 28 which is perforated at 29. These tongues of the caps which are in line with each other are lapped at the ridge of theroof (Fig. 4) and. are united pivotally with eachother and with the roof by thesaid bolts. 6 which pass through the perforations 29. The supercarline 25 does not'entirely,

under normal conditions fill the space within the air of L-flangeslS, 19; nor-does the pair o Lflanges entirely fill the space withinthe seam cap, but some play is allowed to the roof sheet flanges between the supercarline and the seam cap. The outer end of the seam cap is' properly notched at 'its corners and portions of the side flanges 27 are bent inward to form end flanges 30 which overlie the outer end of the supercarline. The top of' the seam cap is bent down to form a depending end flange 31 perforated at 32 through its lower part.

This flange 31 is secured by a bolt 33 which passes through the said perforation 32 and through the fascia and side plate (Figs. 3

and 6). Around the perforation 32 is formed 33 and a nail 39 by which the flange is secured to the fascia and side plate. When such hood 35 is employedthe end flange 31 of the seam cap may be omitted, or made shorter; or both the flanges 30 and 31 may be omitted, the hood 35 serving to close the outer end -of the seam cap. The

roof sheets 15 may be additionally secured at the eaves I by sheet clips 40 which overlie the top of the sheet (Fig. 10) and are provided with depending flanges 41 perforated for a bolt 42 and nail 43 passing through or intothe fascia and side plate. The said bolt 42 and nail 43 are arranged below and do not engage .the sheet flange 16. With the clips 40, 41 the -bolts 23 may be omitted, or they may pass through suitable perforations in the flanges41 (Fig. 10) At the ridgeof the roof the seam caps areiconfined by ridge or intersection caps 44 of bent sheet metal or other material having transverse channels 45 to receive the' seam caps and also longitudinal channels 46 to receive the interlocked U-flanges of the roof sheets. The intersection cap is perforated for the bolt 6. This bolt also confines the saddle 47 of the running board 48, the said saddle being supported by the supercarlines 25, seam caps 26, and the intersection cap. The end finishingsheet of the roof (Fig.8) has only one L-flange, its outer end edge being formed with a depending flange 49 which is secured .to the end fascia and end plate by staggered nails'50 (Fig. 2).

51 is'a malleable end ridge cap inclosing the interlocked U-flanges of the roof. sheets at the end ofthe car, and havinga depend-. ing flange 52 secured by a bolt 53 to the end fascia and end plate.

In Fig. 12 is shown a modified form of roof sheet side flange 18, 19" and seam cap 26", combined with the said subcarline. These flanges may be described as Z-flanges, the part -18 being inclined upward, backward and outwardly away from the carline and forming acute angles with the roof sheet and with the flange 19, the latter flange lappingover the supercarline. This seam cap has side flanges 27 whichincline down- Ward and inward parallel with the sheet flanges 18. By this construction the seam cap is interlocked with the sheet flanges for its entire length against upward disengagement. The supercarline eeps the flanges 18, 18 spaced apart so-that the said interlockin arrangement is preserved.

hood or securing this seam cap 26 at the eaves of the car, or, any intersection cap used with it will be correspondingly modified in shape to properly fit it. The cap 26 will be applied to the roof sheetsand super- 7 carlines in position, by sliding it-lon itudinally along said parts and then securing its iImer end by thebolt 6.
